Be it known that il, 'Mannion dent of Charleston, in thecoiinty of Charles- Vton andState ofSouth Carolina, havev invented certain new and -useful Improvements in Fans7 of which the followingjis a specification-i` My invei'it-ion relates tofmotor operated v fansv of that type embodieduin my Patent No. 1,354,098 issued September 28,1920, in which the .rotating fan wheel continuously oscillates through a fixed arc and atthe'same Y time 'bodily rotates so vthattlie path of the arc continuously changesptoveifect Vra diffu-v sion of the air current-producedbytheV fan overa greater and constantly changing area. The purpose `of my present `invention isf the provision of afan of the above described character in which the mechanism for effect-V th'e" oscillation of the Vfan, i-s ,adjustable to vary the'length of the arcof` oscillation.

Another purposek ofthe present invention is to provide afan. in whichthe mechanism for effecting bodily rotation of the fan is adjustable to vary the degree of intermittent rotation, such mechanism Yalso including means for preventing the acci-dental disen- C iiigrrmy'inventicn and willtlien point outj, 5 the Vnovelffeat lires ythereofA in claims.

VReferring specically to the drawings and particularly 4to Figure `1, my invention Vinits present embodiment comprises aVv fan' wheelV W operated by a motonM which is Vsupported Jfor oscillatory movementby a yoke Y.

Theyoke Y in turn is adapted to be suspended from a ceilingso as to be freeV to rotate about a vertical axis throughV thc medium of an axle A which is adapted toibe ixedly secured to the ceiling in `any suitable manner. `The yoke Y includes an Lipper horizontal portion '15 and two vertical portions 16 and 16, the lower ends of' Vwhiclilatte'r are providedwith bearings 17 and17a, respectively; in which are journaled stub axles 18 and 18a, respectively, forsup` porting the fan motor `for oscillatory movement about a horizontal axis. T he axle extends through a bearing 19 formed'in the horizontal portion 15` so that with the yoke secured against"displacement from the axle it is Vfree to :rotate about the axle as a center.

` The oscillatory movement of the motor M" within the yoke Y is effected by a mechanism which as illustrated to advantage" in Figure 2v includesthe motor shaft `20 operatively connected to a counter shaft 21 through the `medium of a worm and worm wheel are' rangement, indicated at 22, all of which are enclosed in a suitable housing 23 V(Figure 1). By this arrangement the shaft 21 projects from the housing 23 and is there provided with a disc'21 reniovablygitted eol will be driven atan appropriately reduced," Vspeed as compared with the speed of thev motor shaft 20. One end of the shaft 21 ioo thereon by a collar 25 and aset screw 2G.-`A4 The disc24 is formed with anA arcuate slot 27 that'is` arranged spirally of the axisiof e the vehicle, and mounted within this slot is a bolt or pin 28 to which is pivotally" con- "neeted one end of fa link "29. .The opposite end of the link 29 is pivotallyl connected to abolt 30 extending into anarcuate s101331 formed in oney arm 32 of a 'plate P. `As

Ashown in Figure 1 this plate P includes another arm 33" disposed at right angles tothe Y arm 3 2 and provided With a slot 34' through motorshaftas a center.V :During oscillation Vio is, imparted y the latten, to

The Vstop 37ZL limits themovement, ofthe engaged by"V the bolts 45 successively. It will thusbe apparent that an intermittent rotation-oi" tlieratchet wheel il is eected. The discs 53 and 55 provide frictional contact sufficient to form an operative connec- VVtion between the yoke Y and the ratchet Wheel 4l' so 'that under the intermittent movement of the latterga corresponding movement ofthe yoke is effected. This obviously'causes an intermittentrotation4 of the motor M about the vertical axis Without interfering` with the oscillatory movement about the horizontal Vaiis. By api-'oper ,adjustment of the screw, plugs 58- friction,

can be set up between the discs'of the clutch suiiicient to fprovide an operative connection oet-Ween the ratchet Wheeland yoke and at the same time tjoprevent4 excessive Vmovement of the Wheel or yokerunder the action .i ot the '.pavvl 39 so that each intermittent rotative movement of the. motor canV be-'of a predetermined distance thus rendering thisV rotatinginoveinent uniform and irrespective otthe speedrvvith 'which the motor M oscillates. f V Y Although .I have Vherein shown and described' only one form `ot fan embodied iiiiny invention, it .is Vto be understood that various changesand inodiiicrations maybe Vmade herein Withoutdeparting',from. the
